Thoughts 21

Thoughts 21

Last week we started a mental journey through the solar system, out through our galaxy and on into the local cluster of galaxies to look back at the living organism Earth. That trip took us 3.5 million years traveling at the speed of light and we did not make it to the edge of our Local Cluster. Larger than local clusters are super-clusters.

Let's go and look at some more of the universe. As we leave Local Cluster we can again look back and see that the galaxies are moving in a way that looks somewhat synchronized. All the galaxies of the local group are moving in relation to their center of mass. The mass of the galaxies have warped the fabric of space/time in such a way that they are caught in each others gravity.
Scanning to see what is in front and to the sides of us we see other larger groups of galaxies; super-clusters. Our Local Group is part of the Virgo Super-cluster, which includes the Virgo cluster.


The clusters that make up super-clusters are moving in relation to their center of mass, so I am going to project the super-cluster groups are moving in relation to each other.
To my knowledge the whole of the visible universe has not been mapped but the above and what I have read, leads me to believe all mass is probably interconnected in space/time; maybe with space/time.

Now we have covered hundreds of millions possibly a few billion light years, so I am feeling old.

Galactic Metropolis
The collection of red dots seen near the center of this image show one of several very distant galaxy clusters discovered by combining ground-based optical data from the National Optical Astronomy Observatory's Kitt Peak National Observatory with infrared data from NASA's Spitzer Space Telescope. This galaxy cluster, named ISCS J1434.7+3519, is located about 9 billion light-years from Earth.

The large white and yellow dots in this picture are stars in our galaxy, while the rest of the smaller dots are distant galaxies. The cluster, comprised of red dots near the center, includes more than 100 massive galaxies.
Spitzer was able to capture prodigious levels of star formation occurring in the galaxies that live in this cluster.  Some of them are forming stars hundreds of times faster than our own Milky Way galaxy.
Infrared light in this image has been colored red; and visible light, blue and green.
